"We have recuperated this hospital after 10 years of decay in which it was not looked after," he said, speaking to reporters at the reopening of the Bernardo Houssay public hospital in the coastal city of Mar del Plata.

"We have demonstrated that when we sit down together at the same table, and if we work telling the truth, then all our problems have a solution", he added.

"Now retirees don't have to travel to Buenos Aires to be treated because we have a top rate hospital [in Mar del Plata]," the president said.

Macri visited several locations on his Mar del Plata tour, including a depository of repossessed cars. The 300 vehicles kept at the site are allegedly linked to drug-trafficking crimes.

There, he was joined by Security Minister Patricia Bullrich, whose constant presence alongside Macri since the start of the year during crime and safety-related announcements suggests she will be a key face in the government's 2019 election bid.

The vehicles were impounded in the "Total Clean-up" operation orchestrated by Mar del Plata judge Santiago Ichnausti. Each vehicle was valued at around 700,000 pesos. Fourteen people were arrested in the operation, police reported.
